Hello. I have a Trek 4500 and it has been a great bike. I'm getting clipless pedals for it soon and new red grips. The only problem I have had with it has been low pedal clearence. I've taken my kick stand off so I know its not that. Over roots and log pyramids, the pedals sometimes smack the roots. It throws you off balence. I can hold the pedals parallel to the ground and their is know problem. But up rooty hills, it gets annoying.:mad: What can I do to fix this.

What can I do to fix this.
Shorter cranks(165, 170mm) and smaller pedals, like CB eggbeaters.

Learning to pedal more smoothly, and timing pedal strokes better will do him more good than buying new parts.
Ride more. As the saying goes, practice makes perfect, right?
I've been riding for about seven years, and I still manage to whack my pedals every now and then. Technique, timing, practice will help reduce the incidents, but I don't think one can ever eliminate the occasional whack. It's part of the game.

Not much...you need a frame with a higher bottom bracket...My BB height is over 15" and I still hit things and am thinking of going to 16" with a longer fork
Don't use shorter cranks...you'll have to work much harder and only pick up a few cm in clearance

This is some of the worst advice I've seen on here in a while.

100% agree. Some people come into riding thining cadence is king. In reality its ALSO timing. Timing your stroke to the trail you can make it up some rough stuff. This is a learned trait. To fix it by purchasing new equipment which might affect other parts of your riding isn't the smartest thing to do. It would "work"...but it wouldn't make you a better rider.

Maybe you could put your pedal at a neutral zone, that's how I call it when both your pedals are parallel to the ground...

How do you pedal uphill on roots with your pedals level?...;)

How come?...with 15" BB height, I'm still hitting logs, rocks, and sides of hills with my peddles when I'm in the tight singletrack on the home trails...cadence and riding skills have noyhing to do with this...hopping over a too big a log on a steep descent can still make contact

PRobably because if you watch the better xc guys they can have a lower bb height and not hit anything. While what you say isn't wrong, you aren't becoming a better rider because of it.
And trust me, I know your area fairly well, and if you think you have problems out there you should really come out west. From your description it sounds like you wouldn't even be able to pedal. I used to think like you (god I wanted a tall bike) until I hooked up with some good riders who floated the entire section I was stuck in.
and during dh I would say the forces are different, especially on a dually. Taking turns quickly, landing a jump and other variable can create a lot of force pushing the bike down. Quite a bit different then pedalling.

You don't want a higher bb and you probably don't want shorter crankarms, some DH riders excluded.
You do want to practice more, because it can be done. Believe. :D
Cadence and riding skills have everything to do with it.
Hmmmm...I'm leading two group rides this weekend...one group has a rider who used to race with (not for) the Cdn mtb team...another with a team that's training for the TransRockies in August...
I'll report back on Tuesday as to how we do...perhaps I can lead from the back and watch how they avoid the occassional peddle contact

I have to agree with the timing recommendation. There are times I'll level out my pedals before an obstacle, ratchet one pedal back (if the obstacle is on one side), or some sort of combination. It may be extremely brief but if you do it right, you'll clear.

Man the trans is brutal. My uncle in law has been riding and building trails out here for 20 some odd years. He got back and said that was the first time he ever bonked (he won the first xfc thing) He bonked on day 5 or 6. Definately nuts.

they should do well...they came in the top 5 in last week's 24 hour summer solstice here, even after losing a team member after the 3'rd lap
their training includes pedalling up Blue Mountain in Collingwood 4X/day
could be a fun day
Occasional pedal smacks are part of mountain biking.
that's all I was trying to say...now if I can figure out a way from stopping the pins on my wellgo flats from tearing up my leg...:rolleyes:

Ellsworth Id only has a 13" BB height. JustsayinknowwhatImsayin'?

Welcome to the weird world of Ellsworth
The Id BB height spec'd out at 13.75"
Bottom Bracket Height: 13.75
http://shop.ellsworthbikes.com/bikes/id/index.cfm
but apparently this is the sagged height (makes no sense), and the Id is designed for 4" (Cali version), 5", and 6" rear travel...depends on the shock stroke...1.75", 2.0", or 2.25"
Mine is a 6" (7.875" X 2.25") resulting in an unsagged BB height of just over 15"...proof is in the standover...I now sing soprano in our church choir

I guess I do need to work on timing. I had a guy coming the other way yesterday on a very rooty, and up hill for him area, and he cut through it like a knife through butter. Thanks alot guys.

It's much easier on a hardtail...with a little practice and a dialed in drive train, you can make a bike dance through the crap and corruption
happy trails

There is nothing wrong with your bike, learn to pick the easiest path through is also a major aspect.
It's only to blame on your bike if you are taking the exact same path through as everyone else and you are grinding your chainring, not your pedals.

This was the other aspect I was going to point out. If possible, you may be able to swing a couple-o-more inches in either direction and avoid the obstacle all together.

Not whacking pedals into the ground or your legs is a little peice of your base skillset that develops with time.
If you want to make the most of your saddle time, read Ned Overend How to mtb like a champion. Its an oldie with all kinds of practical tips. Im know it has somestuff about pedal clearance. I read it when i first started and it helped a ton because i had noone to teach me.
